自Symfony 4.3起，不支持在多行块中映射键，并且将在5.0中引发ParseException

Question

我有问题。更新到Symfony 4.4之后，我收到以下弃用警告

Support for mapping keys in multi-line blocks is deprecated since Symfony 4.3 and will throw a ParseException in 5.0.
2x in AccountControllerTest::testSettings from App\Tests\Controller
1x in AccountControllerTest::testPageUser from App\Tests\Controller

我完全不知道这意味着什么。

来自App \ Tests \ Controller的testSettings：

    public function testSettings() {
    $crawler = self::$userClient->request('GET', '/nl/account/settings.html');
    $this->assertSuccesfulResponse(self::$userClient->getResponse());
    $crawler = $this->form(self::$userClient, $crawler, 'submit', array(), '/\/nl\/account/');
}

提前感谢！

这意味着您可能在Yaml文件中的某个位置有一个多行键，而symfony不支持它，而在symfony 5.0中，它将抛出异常而不是警告！

类似的东西：

 this
 is
 multi
 key:  test
